I am using react-create-app
in Windows 10, on February 2nd, 2019 with latest NodeJS 11.9.0 and npm 6.7.0 (When you install NodeJS, the npm
is existing). I think case of node packages are corrupted is rarely, the main cause permission.
At the beginning, I put project directory at Desktop, it is belong to C:\
driver. I move to another directory of another driver. Therefore, I remove "file permission" concern. Every work well and simple.
cd /d D:\
mkdir temp20190202
npx create-react-app my-app
cd my-app
npm start
It is ok, not put project folder in a directory of C:\
(or other driver what contains Windows Operating system).
This should work, at least according to the Search Filter Syntax article on MSDN network.
The "hang-up" you have noticed is probably just a delay. Try running the same query with narrower scope (for example the specific OU where the test object is located), as it may take very long time for processing if you run it against all AD objects.
You may also try separating the filter into two parts:
(|(displayName=*searchstring)(displayName=searchstring*))
jQuery < 1.8
May I suggest that you use $.ajax()
instead of $.post()
as it's much more customizable.
If you are calling $.post()
, e.g., like this:
$.post( url, data, success, dataType );
You could turn it into its $.ajax()
equivalent:
$.ajax({
type: 'POST',
url: url,
data: data,
success: success,
dataType: dataType,
async:false
});
Please note the async:false
at the end of the $.ajax()
parameter object.
Here you have a full detail of the $.ajax()
parameters: jQuery.ajax() – jQuery API Documentation.
jQuery >=1.8 "async:false" deprecation notice
jQuery >=1.8 won't block the UI during the http request, so we have to use a workaround to stop user interaction as long as the request is processed. For example:
$.ajax()
, and then remove it when the AJAX .done()
callback is called.Please have a look at this answer for an example.
Not sure if this is what you were looking for, but this worked for me:
$query = query("DESC YourTable");
$col_names = array_column($query, 'Field');
That returns a simple array of the column names / variable names in your table or array as strings, which is what I needed to dynamically build MySQL queries. My frustration was that I simply don't know how to index arrays in PHP very well, so I wasn't sure what to do with the results from DESC or SHOW. Hope my answer is helpful to beginners like myself!
To check result: print_r($col_names);
Can also do more dynamic inits with fill, e.g.
Array.fill(10){scala.util.Random.nextInt(5)}
==>
Array[Int] = Array(0, 1, 0, 0, 3, 2, 4, 1, 4, 3)
According to the documentation for UIButton:
In iOS v7.0, all subclasses of UIView derive their behavior for tintColor from the base class. See the discussion of tintColor at the UIView level for more information.
Assuming you don't change the tintColor before grabbing the default value, you can use:
self.view.tintColor
Q1:
$(document).ready(function() {
var totalMinutes = $('.totalMin').html();
var hours = Math.floor(totalMinutes / 60);
var minutes = totalMinutes % 60;
$('.convertedHour').html(hours);
$('.convertedMin').html(minutes);
});
Q2:
$(document).ready(function() {
var minutes = 0;
$('.min').each(function() {
minutes = parseInt($(this).html()) + minutes;
});
var realmin = minutes % 60
var hours = Math.floor(minutes / 60)
$('.hour').each(function() {
hours = parseInt($(this).html()) + hours;
});
$('.totalHour').html(hours);
$('.totalMin').html(realmin);
});
Check your npm
version
If it's not properly installed, then install it first
run this command npm install typescript -g
now tsc <file_name>.ts
It'll create a corresponding .js
file. eg <file_name>.js
now try node <file_name>.js
Using DirectoryIterator an equivalent of a previous answer…
function deleteFolder($rootPath)
{
foreach(new DirectoryIterator($rootPath) as $fileToDelete)
{
if($fileToDelete->isDot()) continue;
if ($fileToDelete->isFile())
unlink($fileToDelete->getPathName());
if ($fileToDelete->isDir())
deleteFolder($fileToDelete->getPathName());
}
rmdir($rootPath);
}
Suppose you want to check a boolean. If true, do something. Else, do something else. You can write:
if(condition==true){
}
else{ //else means this checks for the opposite of what you checked at if
}
instead of that, you can do it simply like:
if(condition){ //this will check if condition is true
}
else{
}
Inversely. If you were to do something if condition was false and do something else if condition was true. Then you would write:
if(condition!=true){ //if(condition=false)
}
else{
}
But following the simple path. We do:
if(!condition){ //it reads out as: if condition is not true. Which means if condition is false right?
}
else{
}
Think about it. You'll get it in no time.
UPDATE:
This answer is 6 years old and very outdated, but it's still attracting votes and comments. Ever since iOS 6.0 you should be using the pageIndicatorTintColor
and currentPageIndicatorTintColor
properties on UIPageControl
.
ORIGINAL ANSWER:
I ran into this problem today and decided to write my own simple replacement class.
It's a sublassed UIView that uses Core Graphics to render the dots in the colors you specify.
You use the exposed properties to customize and control it.
If you want to you can register a delegate object to get notifications when the user taps on one of the little page dots. If no delegate is registered then the view will not react to touch input.
It's completely fresh from the oven, but seems to work. Let me know if you run into any problems with it.
Future improvements:
Example use:
CGRect f = CGRectMake(0, 0, 320, 20);
PageControl *pageControl = [[[PageControl alloc] initWithFrame:f] autorelease];
pageControl.numberOfPages = 10;
pageControl.currentPage = 5;
pageControl.delegate = self;
[self addSubview:pageControl];

You need to use kill -9 59780
with 59780
replaced with found PID number (use lsof -wni tcp:3000
to see which process used 3000
port and get the process PID).
Or you can just modify your puma config change the tcp port tcp://127.0.0.1:3000
from 3000
to 9292
or other port that not been used.
Or you can start your rails app by using:
bundle exec puma -C config/puma.rb -b tcp://127.0.0.1:3001
You access the last element of the set and then store the value in a variable.
So you have:
fileName = '7.3\n'
then just do:
fileName.strip()
which will leave you with 7.3
. Then store that value back in the last element of the set.
You can use lstrip()
or rstrip()
to remove just the left or right side.
Put the text file in the assets directory. If there isnt an assets dir create one in the root of the project. Then you can use Context.getAssets().open("BlockForTest.txt");
to open a stream to this file.
I know this is an old thread, but for others looking, the above solutions are maybe not as good as the following, instead of checking change
events, check the input
events.
$("#myInput").on("input", function() {
// Print entered value in a div box
$("#result").text($(this).val());
});
If bitsadmin isn't your cup of tea, you can use this PowerShell command:
Start-BitsTransfer -Source http://www.foo.com/package.zip -Destination C:\somedir\package.zip
Both, FILL_PARENT
and MATCH_PARENT
are the same properties. FILL_PARENT
was deprecated in API level 8.
My original answer was written in 2009. While it still works, I'd like to update it for 2017. Browsers can still behave differently. I trust the jQuery team to do a great job at maintaining cross-browser consistency. However, it's not necessary to include the entire library. In the jQuery source, the relevant portion is found on line 37 of dimensions.js. Here it is extracted and modified to work standalone:
function getWidth() {_x000D_
return Math.max(_x000D_
document.body.scrollWidth,_x000D_
document.documentElement.scrollWidth,_x000D_
document.body.offsetWidth,_x000D_
document.documentElement.offsetWidth,_x000D_
document.documentElement.clientWidth_x000D_
);_x000D_
}_x000D_
_x000D_
function getHeight() {_x000D_
return Math.max(_x000D_
document.body.scrollHeight,_x000D_
document.documentElement.scrollHeight,_x000D_
document.body.offsetHeight,_x000D_
document.documentElement.offsetHeight,_x000D_
document.documentElement.clientHeight_x000D_
);_x000D_
}_x000D_
_x000D_
console.log('Width: ' + getWidth() );_x000D_
console.log('Height: ' + getHeight() );
_x000D_
Since all browsers behave differently, you'll need to test for values first, and then use the correct one. Here's a function that does this for you:
function getWidth() {
if (self.innerWidth) {
return self.innerWidth;
}
if (document.documentElement && document.documentElement.clientWidth) {
return document.documentElement.clientWidth;
}
if (document.body) {
return document.body.clientWidth;
}
}
and similarly for height:
function getHeight() {
if (self.innerHeight) {
return self.innerHeight;
}
if (document.documentElement && document.documentElement.clientHeight) {
return document.documentElement.clientHeight;
}
if (document.body) {
return document.body.clientHeight;
}
}
Call both of these in your scripts using getWidth()
or getHeight()
. If none of the browser's native properties are defined, it will return undefined
.
The key is "I installed the postgres.app for mac." This application sets up the local PostgreSQL installation with a database superuser whose role name is the same as your login (short) name.
When Postgres.app first starts up, it creates the $USER database, which is the default database for psql when none is specified. The default user is $USER, with no password.
Some scripts (e.g., a database backup created with pgdump
on a Linux systsem) and tutorials will assume the superuser has the traditional role name of postgres
.
You can make your local install look a bit more traditional and avoid these problems by doing a one time:
/Applications/Postgres.app/Contents/Versions/9.*/bin/createuser -s postgres
which will make those FATAL: role "postgres" does not exist go away.
There is no built in function for this.
You could use a CASE statement:
CASE WHEN MonthName= 'January' THEN 1
WHEN MonthName = 'February' THEN 2
...
WHEN MonthName = 'December' TNEN 12
END AS MonthNumber
or create a lookup table to join against
CREATE TABLE Months (
MonthName VARCHAR(20),
MonthNumber INT
);
INSERT INTO Months
(MonthName, MonthNumber)
SELECT 'January', 1
UNION ALL
SELECT 'February', 2
UNION ALL
...
SELECT 'December', 12;
SELECT t.MonthName, m.MonthNumber
FROM YourTable t
INNER JOIN Months m
ON t.MonthName = m.MonthName;
You can change the colour two ways; through XML or through coding. I would recommend XML since it's easier to follow for beginners.
XML:
<Button
android:background="@android:color/white"
android:textColor="@android:color/black"
/>
You can also use hex values ex.
android:background="@android:color/white"
Coding:
//btn represents your button object
btn.setBackgroundColor(Color.WHITE);
btn.setTextColor(Color.BLACK);
I have been banging my head against the wall with a similar problem. The only thing that helped is following the steps in this post.
The Android Tools are still incompatible with JDK 9 or 10. You need to install JDK 8 or, if you need multiple Java versions make sure that the system-wide Java home points to a JDK 8.
More details here: How to configure Unity 2017.4 to target Android and avoid build failures on OSX?
Why not just convert all <button>
to <span>
with type="button"
and then style with your normal css button classes? Just confirmed that this works in IE11.
you could do
distinct_column = 'somecol'
distinct_column_vals = df.select(distinct_column).distinct().collect()
distinct_column_vals = [v[distinct_column] for v in distinct_column_vals]
Other people's suggestions about ~/.ssh/config
are extra complicated. It can be as simple as:
Host github.com
IdentityFile ~/.ssh/github_rsa
You must turn debug off for database in config/database.php ->
$db['default']['db_debug'] = FALSE;
It is better for your website security.
You can actualy fake the transparency of option
DOMElements with the following CSS:
option {
/* Whatever color you want */
background-color: #82caff;
}
The option
tag does not support rgba
colors yet.
The trick here is to put the library AFTER the module you are compiling. The problem is a reference thing. The linker resolves references in order, so when the library is BEFORE the module being compiled, the linker gets confused and does not think that any of the functions in the library are needed. By putting the library AFTER the module, the references to the library in the module are resolved by the linker.
best way is to create an accessor like this:
/**
* @var object $db : map to database connection.
*/
public static $db= null;
/**
* db Function for initializing variable.
* @return object
*/
public static function db(){
if( !isset(static::$db) ){
static::$db= new \Helpers\MySQL( array(
"hostname"=> "localhost",
"username"=> "root",
"password"=> "password",
"database"=> "db_name"
)
);
}
return static::$db;
}
then you can do static::db(); or self::db(); from anywhere.
I have struggled with this when trying to remotely connect to a new PostgreSQL installation on my Raspberry Pi. Here's the full breakdown of what I did to resolve this issue:
First, open the PostgreSQL configuration file and make sure that the service is going to listen outside of localhost.
sudo [editor] /etc/postgresql/[version]/main/postgresql.conf
I used nano
, but you can use the editor of your choice, and while I have version 9.1
installed, that directory will be for whichever version you have installed.
Search down to the section titled 'Connections and Authentication'. The first setting should be 'listen_addresses'
, and might look like this:
#listen_addresses = 'localhost' # what IP address(es) to listen on;
The comments to the right give good instructions on how to change this field, and using the suggested '*'
for all will work well.
Please note that this field is commented out with #. Per the comments, it will default to 'localhost', so just changing the value to '*'
isn't enough, you also need to uncomment the setting by removing the leading #
.
It should now look like this:
listen_addresses = '*' # what IP address(es) to listen on;
You can also check the next setting, 'port', to make sure that you're connecting correctly. 5432 is the default, and is the port that psql will try to connect to if you don't specify one.
Save and close the file, then open the Client Authentication config file, which is in the same directory:
sudo [editor] /etc/postgresql/[version]/main/pg_hba.conf
I recommend reading the file if you want to restrict access, but for basic open connections you'll jump to the bottom of the file and add a line like this:
host all all all md5
You can press tab instead of space to line the fields up with the existing columns if you like.
Personally, I instead added a row that looked like this:
host [database_name] pi 192.168.1.0/24 md5
This restricts the connection to just the one user and just the one database on the local area network subnet.
Once you've saved changes to the file you will need to restart the service to implement the changes.
sudo service postgresql restart
Now you can check to make sure that the service is openly listening on the correct port by using the following command:
sudo netstat -ltpn
If you don't run it as elevated (using sudo
) it doesn't tell you the names of the processes listening on those ports.
One of the processes should be Postgres, and the Local Address should be open (0.0.0.0) and not restricted to local traffic only (127.0.0.1). If it isn't open, then you'll need to double check your config files and restart the service. You can again confirm that the service is listening on the correct port (default is 5432
, but your configuration could be different).
Finally you'll be able to successfully connect from a remote computer using the command:
psql -h [server ip address] -p [port number, optional if 5432] -U [postgres user name] [database name]
Here are the differences that can help you understand the advantages of persist and save methods:
The persist() method doesn’t guarantee that the identifier value will be assigned to the persistent state immediately, the assignment might happen at flush time.
The persist() method will not execute an insert query if it is called outside of transaction boundaries. While, the save() method returns an identifier so that an insert query is executed immediately to get the identifier, no matter if it are inside or outside of a transaction.
The persist method is called outside of transaction boundaries, it is useful in long-running conversations with an extended Session context. On the other hand save method is not good in a long-running conversation with an extended Session context.
Fifth difference between save and persist method in Hibernate: persist is supported by JPA, while save is only supported by Hibernate.
You can see the full working example from the post Difference between save and persist method in Hibernate
The input operator for number skips leading whitespace, so you can just read the number in a loop:
while (myfile >> a)
{
// ...
}
You're not actually returning anything from your run_cmd function.
function run_cmd(cmd, args, done) {
var spawn = require("child_process").spawn;
var child = spawn(cmd, args);
var result = { stdout: "" };
child.stdout.on("data", function (data) {
result.stdout += data;
});
child.stdout.on("end", function () {
done();
});
return result;
}
> foo = run_cmd("ls", ["-al"], function () { console.log("done!"); });
{ stdout: '' }
done!
> foo.stdout
'total 28520...'
Works just fine. :)
cPickle
comes with the standard library… in python 2.x. You are on python 3.x, so if you want cPickle
, you can do this:
>>> import _pickle as cPickle
However, in 3.x, it's easier just to use pickle
.
No need to install anything. If something requires cPickle
in python 3.x, then that's probably a bug.
Try to use:
pattern="(0?[1-9]|[12][0-9]|3[01])/(0?[1-9]|1[012])/\d{4}"
Just for future reference, if you already have a boolean column and you just want to add a default do:
ALTER TABLE users
ALTER COLUMN priv_user SET DEFAULT false;
I could NOT solve this. I had CORS enabled and working as long as the POST returned void (ASP.NET 4.0 - WEBAPI 1). When I tried to return a HttpResponseMessage, I started getting the HTTP 405 response.
Based on Llad's response above, I took a look at my own references.
I had the attribute [System.Web.Mvc.HttpPost] listed above my POST method.
I changed this to use:
[System.Web.Http.HttpPostAttribute]
[HttpOptions]
public HttpResponseMessage Post(object json)
{
...
return new HttpResponseMessage { StatusCode = HttpStatusCode.OK };
}
This fixed my woes. I hope this helps someone else.
For the sake of completeness, I had the following in my web.config:
<httpProtocol>
<customHeaders>
<clear />
<add name="Access-Control-Expose-Headers " value="WWW-Authenticate"/>
<add name="Access-Control-Allow-Origin" value="*" />
<add name="Access-Control-Allow-Methods" value="GET, POST, OPTIONS, PUT, PATCH, DELETE" />
<add name="Access-Control-Allow-Headers" value="accept, authorization, Content-Type" />
<remove name="X-Powered-By" />
</customHeaders>
</httpProtocol>
According to python docs:
has_key()
is deprecated in favor ofkey in d

You may want to check out Marc Liyanage's PHP package. It comes in a nice Mac OS X installer package that you can double-click. He keeps it pretty up to date.
Also, although upgrading to Snow Leopard won't help you do PHP updates in the future, it will probably give you a newer version of PHP. I'm running OS X 10.6.2 and it has PHP 5.3.0.
> use the -O option. [...] If the tar file is corrupt, the process will abort with an error.
Sometimes yes, but sometimes not. Let's see an example of a corrupted file:
echo Pete > my_name
tar -cf my_data.tar my_name
# // Simulate a corruption
sed < my_data.tar 's/Pete/Fool/' > my_data_now.tar
# // "my_data_now.tar" is the corrupted file
tar -xvf my_data_now.tar -O
It shows:
my_name
Fool
Even if you execute
echo $?
tar said that there was no error:
0
but the file was corrupted, it has now "Fool" instead of "Pete".
If you want to remove all whitespace:
$str = preg_replace('/\s+/', '', $str);
See the 5th example on the preg_replace documentation. (Note I originally copied that here.)
Edit: commenters pointed out, and are correct, that str_replace
is better than preg_replace
if you really just want to remove the space character. The reason to use preg_replace
would be to remove all whitespace (including tabs, etc.).
You can't single out individual columns in a cell in that manner. In my opinion, your best option is to add a style='padding-left:10px'
on the second column and apply the styles on an internal div or element. This way you can achieve the illusion of a greater space.

The other answers are generally correct and all outdated. Do use java.time, the modern Java date and time API, for your date and time work. With java.time your job has also become a lot easier compared to the situation when this question was asked in February 2014.
String dateTimeString = "2014-01-16T10:25:00";
LocalDateTime dateTime = LocalDateTime.parse(dateTimeString);
LocalDateTime now = LocalDateTime.now(ZoneId.systemDefault());
if (dateTime.isBefore(now)) {
System.out.println(dateTimeString + " is in the past");
} else if (dateTime.isAfter(now)) {
System.out.println(dateTimeString + " is in the future");
} else {
System.out.println(dateTimeString + " is now");
}
When running in 2020 output from this snippet is:
2014-01-16T10:25:00 is in the past
Since your string doesn’t inform of us any time zone or UTC offset, we need to know what was understood. The code above uses the device’ time zone setting. For a known time zone use like for example ZoneId.of("Asia/Ulaanbaatar")
. For UTC specify ZoneOffset.UTC
.
I am exploiting the fact that your string is in ISO 8601 format. The classes of java.time parse the most common ISO 8601 variants without us having to give any formatter.
java.time works nicely on both older and newer Android devices. It just requires at least Java 6.

}
javascript:
var element = document.getElementById('element');
if(element.style.visibility == 'hidden'){
alert('hidden');
}
else
{
alert('visible');
}
It works for any css property and is very versatile and reliable.
Just add this top of your controller.
use DB;
You need to escape the slashes as %2F
.
Use this:
let oldArray = [1, 2, 3, 4, 5];
let newArray = oldArray.slice();
console.log({newArray});
_x000D_
Basically, the slice()
operation clones the array and returns a reference to a new array.
For references, strings and numbers (and not the actual object), slice()
copies object references into the new array. Both the original and new array refer to the same object. If a referenced object changes, the changes are visible to both the new and original arrays.
Primitives such as strings and numbers are immutable, so changes to the string or number are impossible.
You may use the different accessors to communicate your intent to someone reading your code, and make it easier to write classes which will work correctly no matter how their public API is called.
class Person
attr_accessor :age
...
end
Here, I can see that I may both read and write the age.
class Person
attr_reader :age
...
end
Here, I can see that I may only read the age. Imagine that it is set by the constructor of this class and after that remains constant. If there were a mutator (writer) for age and the class were written assuming that age, once set, does not change, then a bug could result from code calling that mutator.
But what is happening behind the scenes?
If you write:
attr_writer :age
That gets translated into:
def age=(value)
@age = value
end
If you write:
attr_reader :age
That gets translated into:
def age
@age
end
If you write:
attr_accessor :age
That gets translated into:
def age=(value)
@age = value
end
def age
@age
end
Knowing that, here's another way to think about it: If you did not have the attr_... helpers, and had to write the accessors yourself, would you write any more accessors than your class needed? For example, if age only needed to be read, would you also write a method allowing it to be written?

You can also use datetime
:
>>> import datetime
>>> datetime.datetime.fromtimestamp(1347517370).strftime('%c')
'2012-09-13 02:22:50'
Run:
git remote prune origin
Deletes all stale tracking branches which have already been removed at origin
but are still locally available in remotes/origin
.
git gc --auto
'G arbage C ollection' - runs housekeeping tasks (compresses revisions, removes loose/inaccessible objects). The --auto
flag first determines whether any work is required, and exits without doing anything if not.
sys.tables
Contains all tables. so exec this query to get all tables with details.
SELECT * FROM sys.tables
or simply select Name from sys.tables to get the name of all tables.
SELECT Name From sys.tables
If you are using the Office 365 SMTP gateway then "SMTP Error: data not accepted." is the response you will get if the mailbox is full (even if you are just sending from it).
Try deleting some messages out of the mailbox.
If you find any ... let me know!
Seriously, as Josh Smith points out in this post, it's amazing there isn't a CodePlex community or something for this. Heck, it is amazing that there aren't more for purchase!
The only one that I have found (for sale) is reuxables. A little pricey, if you ask me, but you do get 9 themes/61 variations.
After I posted my answer, I thought, heck, I should go see if any CodePlex project exists for this already. I didn't find any specific project just for themes, but I did discover the WPF Contrib project ... which does have 1 theme that they never released.
Rudi Grobler (above) just created CodePlex community for this ... starting with converted themes he mentions above. See his blog post for more info. Way to go Rudi!
As another answer below has mentioned, since this question and my answer were written, the WPF Toolkit has incorporated some free themes, in particular, the themes from the Silverlight Toolkit. Rudi's project goes a little further and adds several more ... but depending on your situation, the WPF Toolkit might be all you need (and you might be installing it already).
df_buy['BUY'] = df_buy['BUY'].astype('float')

To use function LEFT if not all data is in the form '1/12' you need this in the second line above:
Set Col2 = LEFT(Col1, ISNULL(NULLIF(CHARINDEX('/', Col1) - 1, -1), LEN(Col1)))
Or you can try something like this:
Html.DropDownList("Types", Model.Types, new { @readonly = "true" })
You can set the format you want:
dataGridViewCellStyle.Format = "dd/MM/yyyy";
this.date.DefaultCellStyle = dataGridViewCellStyle;
// date being a System.Windows.Forms.DataGridViewTextBoxColumn
If you start tinkering with VirtualBox network settings, watch out for this: you might make new network adapters (eth1, eth2), yet have your /etc/network/interfaces
still configured for eth0.
Diagnose:
ethtool -i eth0
Cannot get driver information: no such device
Find your interfaces:
ls /sys/class/net
eth1 eth2 lo
Fix it:
Edit /etc/networking/interfaces
and replace eth0 with the appropriate interface name (e.g eth1, eth2, etc.)
:%s/eth0/eth2/g
This should work...
var displayDate = new Date().toLocaleDateString();
alert(displayDate);
But I suspect you are trying it on something else, for example:
var displayDate = Date.now.toLocaleDateString(); // No!
alert(displayDate);
I answered something like this in another question already, but will change it just a little for this one.
Unfortunately, there is no getImageResource()
or getDrawableId()
. But, I created a simple workaround by using the ImageView tags.
In onCreate():
imageView0 = (ImageView) findViewById(R.id.imageView0);
imageView1 = (ImageView) findViewById(R.id.imageView1);
imageView2 = (ImageView) findViewById(R.id.imageView2);
imageView0.setTag(R.drawable.apple);
imageView1.setTag(R.drawable.banana);
imageView2.setTag(R.drawable.cereal);
Then, if you like, you can create a simple function to get the drawable id:
private int getDrawableId(ImageView iv) {
return (Integer) iv.getTag();
}
Too easy.
No internal means, AFAIK. Use this: memset(c, 0, length);
I've had the same problem; my MAIL_ENCRYPTION
was tls
on mail.php
but it was null
on .env
file.
So I changed null
to tls
and it worked!
JavaScript:
function submitForm() {
var data1 = new FormData($('input[name^="file"]'));
$.each($('input[name^="file"]')[0].files, function(i, file) {
data1.append(i, file);
});
$.ajax({
url: "<?php echo base_url() ?>employee/dashboard2/test2",
type: "POST",
data: data1,
enctype: 'multipart/form-data',
processData: false, // tell jQuery not to process the data
contentType: false // tell jQuery not to set contentType
}).done(function(data) {
console.log("PHP Output:");
console.log(data);
});
return false;
}
PHP:
public function upload_file() {
foreach($_FILES as $key) {
$name = time().$key['name'];
$path = 'upload/'.$name;
@move_uploaded_file($key['tmp_name'], $path);
}
}
Have you considered using the CCR since you are writing to separate files you can do everything in parallel (read and write) and the CCR makes it very easy to do this.
static void Main(string[] args)
{
Dispatcher dp = new Dispatcher();
DispatcherQueue dq = new DispatcherQueue("DQ", dp);
Port<long> offsetPort = new Port<long>();
Arbiter.Activate(dq, Arbiter.Receive<long>(true, offsetPort,
new Handler<long>(Split)));
FileStream fs = File.Open(file_path, FileMode.Open);
long size = fs.Length;
fs.Dispose();
for (long i = 0; i < size; i += split_size)
{
offsetPort.Post(i);
}
}
private static void Split(long offset)
{
FileStream reader = new FileStream(file_path, FileMode.Open,
FileAccess.Read);
reader.Seek(offset, SeekOrigin.Begin);
long toRead = 0;
if (offset + split_size <= reader.Length)
toRead = split_size;
else
toRead = reader.Length - offset;
byte[] buff = new byte[toRead];
reader.Read(buff, 0, (int)toRead);
reader.Dispose();
File.WriteAllBytes("c:\\out" + offset + ".txt", buff);
}
This code posts offsets to a CCR port which causes a Thread to be created to execute the code in the Split method. This causes you to open the file multiple times but gets rid of the need for synchronization. You can make it more memory efficient but you'll have to sacrifice speed.
If you don't want to hardcode the CSS into a CSS block/file, you can use jQuery to dynamically add CSS to HTML Elements, ID's, and Classes.
$(document).ready(function() {
//Build your CSS.
var body_tag_css = {
"background-color": "#ddd",
"font-weight": "",
"color": "#000"
}
//Apply your CSS to the body tag. You can enter any tag here, as
//well as ID's and Classes.
$("body").css(body_tag_css);
});
I did this in MonoTouch in the following method, I'm sure a pure Obj-C based approach wouldn't be too different. I used this inside a class which had changing URLs at times which is why I just didn't put it in a if/elseif statement.
NSString *myUrls = @"fb://profile/100000369031300|http://www.facebook.com/ytn3rd";
NSArray *urls = [myUrls componentsSeparatedByString:@"|"];
for (NSString *url in urls){
NSURL *nsurl = [NSURL URLWithString:url];
if ([[UIApplication sharedApplication] canOpenURL:nsurl]){
[[UIApplication sharedApplication] openURL:nsurl];
break;
}
}
The break is not always called before your app changes to Safari/Facebook. I assume your program will halt there and call it when you come back to it.
As mentioned by Zeeshan, the logrotate options size
, minsize
, maxsize
are triggers for rotation.
To better explain it. You can run logrotate as often as you like, but unless a threshold is reached such as the filesize being reached or the appropriate time passed, the logs will not be rotated.
The size options do not ensure that your rotated logs are also of the specified size. To get them to be close to the specified size you need to call the logrotate program sufficiently often. This is critical.
For log files that build up very quickly (e.g. in the hundreds of MB a day), unless you want them to be very large you will need to ensure logrotate is called often! this is critical.
Therefore to stop your disk filling up with multi-gigabyte log files you need to ensure logrotate is called often enough, otherwise the log rotation will not work as well as you want.
on Ubuntu, you can easily switch to hourly rotation by moving the script /etc/cron.daily/logrotate to /etc/cron.hourly/logrotate
Or add
*/5 * * * * /etc/cron.daily/logrotate
To your /etc/crontab file. To run it every 5 minutes.
The size
option ignores the daily, weekly, monthly time options. But minsize & maxsize take it into account.
The man page is a little confusing there. Here's my explanation.
minsize
rotates only when the file has reached an appropriate size and the set time period has passed. e.g. minsize 50MB + daily
If file reaches 50MB before daily time ticked over, it'll keep growing until the next day.
maxsize
will rotate when the log reaches a set size or the appropriate time has passed.
e.g. maxsize 50MB + daily.
If file is 50MB and we're not at the next day yet, the log will be rotated. If the file is only 20MB and we roll over to the next day then the file will be rotated.
size
will rotate when the log > size. Regardless of whether hourly/daily/weekly/monthly is specified. So if you have size 100M - it means when your log file is > 100M the log will be rotated if logrotate is run when this condition is true. Once it's rotated, the main log will be 0, and a subsequent run will do nothing.
So in the op's case. Specficially 50MB max I'd use something like the following:
/var/log/logpath/*.log {
maxsize 50M
hourly
missingok
rotate 8
compress
notifempty
nocreate
}
Which means he'd create 8hrs of logs max. And there would be 8 of them at no more than 50MB each. Since he's saying that he's getting multi gigabytes each day and assuming they build up at a fairly constant rate, and maxsize is used he'll end up with around close to the max reached for each file. So they will be likely close to 50MB each. Given the volume they build, he would need to ensure that logrotate is run often enough to meet the target size.
Since I've put hourly there, we'd need logrotate to be run a minimum of every hour. But since they build up to say 2 gigabytes per day and we want 50MB... assuming a constant rate that's 83MB per hour. So you can imagine if we run logrotate every hour, despite setting maxsize to 50 we'll end up with 83MB log's in that case. So in this instance set the running to every 30 minutes or less should be sufficient.
Ensure logrotate is run every 30 mins.

String.Concat transforms DBNull and null values to an empty string.
public string GetCustomerNumber(Guid id)
{
object accountNumber =
(object)DBSqlHelperFactory.ExecuteScalar(connectionStringSplendidCRM,
CommandType.StoredProcedure,

new SqlParameter("@id", id));
return String.Concat(accountNumber);
}
However, I think you lose something on code understandability
You can't put a border on a tr element. This worked for me in firefox and IE 11:
<td style='border-bottom:1pt solid black'>
If the problem is 100% here
EffectSelectorForm effectSelectorForm = new EffectSelectorForm(Effects);
There's only one possible explanation: property/variable "Effects" is not initialized properly... Debug your code to see what you pass to your objects.
EDIT after several hours
There were some problems:
MEF attribute [Import] didn't work as expected, so we replaced it for the time being with a manually populated List<>. While the collection was null, it was causing exceptions later in the code, when the method tried to get the type of the selected item and there was none.
several event handlers weren't wired up to control events
Some problems are still present, but I believe OP's original problem has been fixed. Other problems are not related to this one.
This is actually pretty easy to fix and doesn't take any coding:
1.Click on the Plots tab above the console. 2.Then at the top right corner of the plots screen click on the options button. 3.Lastly uncheck the "Mute inline plotting" button
Now re-run your script and your graphs should show up in the console.
Cheers.
max-age=0, must-revalidate
and no-cache
aren't exactly identical. With must-revalidate
, if the server doesn't respond to a revalidation request, the browser/proxy is supposed to return a 504 error. With no-cache
, it would just show the cached content, which would be probably preferred by the user (better to have something stale than nothing at all). This is why must-revalidate
is intended for critical transactions only.
There is a pandas function that can be applied to DateTime index in pandas data frame.
date = dataframe.index #date is the datetime index
date = dates.strftime('%Y-%m-%d') #this will return you a numpy array, element is string.
dstr = date.tolist() #this will make you numpy array into a list
the element inside the list:
u'1910-11-02'
You might need to replace the 'u'.
There might be some additional arguments that I should put into the previous functions.
Just check the packaging, the simplest answer I can provide is that your package has been mislabeled (within a class).
Also, you may have some weird characters. Try white-flushing the code in a Notepad (or Gedit) and then pasting it into a newly created class with your IDE.
First of all stop the xampp/wamp and then kindly remove the starting semicolon ( ; ) from your xampp/php/php.ini the following code.
;extension=php_intl.dll
And then restart your xampp/wamp.
Change your selector to
val = j$("#select_2 option:selected").text();
You're selecting the <select>
instead of the <option>
Sooo simple to get row count:
cursor = dbObj.rawQuery("select count(*) from TABLE where COLUMN_NAME = '1' ", null);
cursor.moveToFirst();
String count = cursor.getString(cursor.getColumnIndex(cursor.getColumnName(0)));
Unrelated to mockito, one can catch the exception and assert its properties. To verify that the exception did happen, assert a false condition within the try block after the statement that throws the exception.
I deleted folders build
inside a project. After cleaned and rebuilt it in Android Studio. Then corrected errors in build.gradle and AndroidManifest.
There are 2 calls that need to set the correct headers. Initially there is a preflight check so you need something like...
app.get('/item', item.list);
app.options('/item', item.preflight);
and then have the following functions...
exports.list = function (req, res) {
Items.allItems(function (err, items) {
...
res.header('Access-Control-Allow-Origin', "*"); // TODO - Make this more secure!!
res.header('Access-Control-Allow-Methods', 'GET,PUT,POST');
res.header('Access-Control-Allow-Headers', 'Access-Control-Allow-Headers", "Origin, X-Requested-With, Content-Type, Accept');
res.send(items);
}
);
};
and for the pre-flight checks
exports.preflight = function (req, res) {
Items.allItems(function (err, items) {
res.header('Access-Control-Allow-Origin', "*"); // TODO - Make this more secure!!
res.header('Access-Control-Allow-Methods', 'GET,PUT,POST');
res.header('Access-Control-Allow-Headers', 'Access-Control-Allow-Headers", "Origin, X-Requested-With, Content-Type, Accept');
res.send(200);
}
);
};
You can consolidate the res.header() code into a single function if you want.
Also as stated above, be careful of using res.header('Access-Control-Allow-Origin', "*") this means anyone can access your site!
Accepted answer is certainly a good solution, but here is the way I went about generating a CSV and serving it from a view.
Thought it was worth while putting this here as it took me a little bit of fiddling to get all the desirable behaviour (overwrite existing file, storing to the right spot, not creating duplicate files etc).
Django 1.4.1
Python 2.7.3
#Model
class MonthEnd(models.Model):
report = models.FileField(db_index=True, upload_to='not_used')
import csv
from os.path import join
#build and store the file
def write_csv():
path = join(settings.MEDIA_ROOT, 'files', 'month_end', 'report.csv')
f = open(path, "w+b")
#wipe the existing content
f.truncate()
csv_writer = csv.writer(f)
csv_writer.writerow(('col1'))
for num in range(3):
csv_writer.writerow((num, ))
month_end_file = MonthEnd()
month_end_file.report.name = path
month_end_file.save()
from my_app.models import MonthEnd
#serve it up as a download
def get_report(request):
month_end = MonthEnd.objects.get(file_criteria=criteria)
response = HttpResponse(month_end.report, content_type='text/plain')
response['Content-Disposition'] = 'attachment; filename=report.csv'
return response
You can use select into inside of a PLSQL block such as below.
Declare
l_variable assignment%rowtype
begin
select *
into l_variable
from assignment;
exception
when no_data_found then
dbms_output.put_line('No record avialable')
when too_many_rows then
dbms_output.put_line('Too many rows')
end;
This code will only work when there is exactly 1 row in assignment. Usually you will use this kind of code to select a specific row identified by a key number.
Declare
l_variable assignment%rowtype
begin
select *
into l_variable
from assignment
where ID=<my id number>;
exception
when no_data_found then
dbms_output.put_line('No record avialable')
when too_many_rows then
dbms_output.put_line('Too many rows')
end;
You're very close already, you just need to return the new object that you want. In this case, the same one except with the launches value incremented by 10:
var rockets = [_x000D_
{ country:'Russia', launches:32 },_x000D_
{ country:'US', launches:23 },_x000D_
{ country:'China', launches:16 },_x000D_
{ country:'Europe(ESA)', launches:7 },_x000D_
{ country:'India', launches:4 },_x000D_
{ country:'Japan', launches:3 }_x000D_
];_x000D_
_x000D_
var launchOptimistic = rockets.map(function(elem) {_x000D_
return {_x000D_
country: elem.country,_x000D_
launches: elem.launches+10,_x000D_
} _x000D_
});_x000D_
_x000D_
console.log(launchOptimistic);
_x000D_

Following on from Naresh's answer, dynamic polymorphism is only 'dynamic' in Java because of the presence of the virtual machine and its ability to interpret the code at run time rather than the code running natively.
In C++ it must be resolved at compile time if it is being compiled to a native binary using gcc, obviously; however, the runtime jump and thunk in the virtual table is still referred to as a 'lookup' or 'dynamic'. If C inherits B, and you declare B* b = new C(); b->method1();
, b will be resolved by the compiler to point to a B object inside C (for a simple class inherits a class situation, the B object inside C and C will start at the same memory address so nothing is required to be done; it will be pointing at the vptr that they both use). If C inherits B and A, the virtual function table of the A object inside C entry for method1 will have a thunk which will offset the pointer to the start of the encapsulating C object and then pass it to the real A::method1() in the text segment which C has overridden. For C* c = new C(); c->method1()
, c will be pointing to the outer C object already and the pointer will be passed to C::method1() in the text segment. Refer to: http://www.programmersought.com/article/2572545946/
In java, for B b = new C(); b.method1();
, the virtual machine is able to dynamically check the type of the object paired with b and can pass the correct pointer and call the correct method. The extra step of the virtual machine eliminates the need for virtual function tables or the type being resolved at compile time, even when it could be known at compile time. It's just a different way of doing it which makes sense when a virtual machine is involved and code is only compiled to bytecode.
The exact code will vary for each of the columns you want to do, but it's likely you'll want to use the map
and apply
functions. In some cases you can just compute using the existing columns directly, since the columns are Pandas Series objects, which also work as Numpy arrays, which automatically work element-wise for usual mathematical operations.
>>> d
A B C
0 11 13 5
1 6 7 4
2 8 3 6
3 4 8 7
4 0 1 7
>>> (d.A + d.B) / d.C
0 4.800000
1 3.250000
2 1.833333
3 1.714286
4 0.142857
>>> d.A > d.C
0 True
1 True
2 True
3 False
4 False
If you need to use operations like max and min within a row, you can use apply
with axis=1
to apply any function you like to each row. Here's an example that computes min(A, B)-C
, which seems to be like your "lower wick":
>>> d.apply(lambda row: min([row['A'], row['B']])-row['C'], axis=1)
0 6
1 2
2 -3
3 -3
4 -7
Hopefully that gives you some idea of how to proceed.
Edit: to compare rows against neighboring rows, the simplest approach is to slice the columns you want to compare, leaving off the beginning/end, and then compare the resulting slices. For instance, this will tell you for which rows the element in column A is less than the next row's element in column C:
d['A'][:-1] < d['C'][1:]
and this does it the other way, telling you which rows have A less than the preceding row's C:
d['A'][1:] < d['C'][:-1]
Doing ['A"][:-1]
slices off the last element of column A, and doing ['C'][1:]
slices off the first element of column C, so when you line these two up and compare them, you're comparing each element in A with the C from the following row.
These are configurable variables in php.ini:
; with sane limits
xdebug.var_display_max_depth = 10
xdebug.var_display_max_children = 256
xdebug.var_display_max_data = 1024
; with no limits
; (maximum nesting is 1023)
xdebug.var_display_max_depth = -1
xdebug.var_display_max_children = -1
xdebug.var_display_max_data = -1
Of course, these may also be set at runtime via ini_set()
, useful if you don't want to modify php.ini and restart your web server but need to quickly inspect something more deeply.
ini_set('xdebug.var_display_max_depth', '10');
ini_set('xdebug.var_display_max_children', '256');
ini_set('xdebug.var_display_max_data', '1024');
Xdebug settings are explained in the official documentation.
Change your code to:
System.out.println("AM or PM?");
Scanner TimeOfDayQ = new Scanner(System.in);
TimeOfDayStringQ = TimeOfDayQ.next();
if(!TimeOfDayStringQ.equals("AM") && !TimeOfDayStringQ.equals("PM")) { // <--
System.out.println("Sorry, incorrect input.");
System.exit(1);
}
...
if(Hours == 13){
if (TimeOfDayStringQ.equals("AM")) {
TimeOfDayStringQ = "PM"; // <--
} else {
TimeOfDayStringQ = "AM"; // <--
}
Hours = 1;
}
}
It is possible to edit same file in Split mode. It is best explained in following youtube video.
If by "empty" you mean undefined
, it is the way ng-expressions are interpreted. Then, you could use :
<a ng-if="!item.photo" href="#/details/{{item.id}}"><img src="/img.jpg" class="img-responsive"></a>
You can use Jackson API as well for this :
final String json = "....your json...";
final ObjectMapper mapper = new ObjectMapper();
final MapType type = mapper.getTypeFactory().constructMapType(
Map.class, String.class, Object.class);
final Map<String, Object> data = mapper.readValue(json, type);
When you want to test a state of application and in case of a problem return HTTP error I would suggest a filter. The filter below handles all HTTP requests. The shortest solution in Spring Boot with a javax filter.
In the implementation can be various conditions. In my case the applicationManager testing if the application is ready.
import ...ApplicationManager;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Component;
import javax.servlet.*;
import javax.servlet.http.HttpServletResponse;
import java.io.IOException;
@Component
public class SystemIsReadyFilter implements Filter {
@Autowired
private ApplicationManager applicationManager;
@Override
public void init(FilterConfig filterConfig) throws ServletException {}
@Override
public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain) throws IOException, ServletException {
if (!applicationManager.isApplicationReady()) {
((HttpServletResponse) response).sendError(HttpServletResponse.SC_SERVICE_UNAVAILABLE, "The service is booting.");
} else {
chain.doFilter(request, response);
}
}
@Override
public void destroy() {}
}
You can do this with two options.
first simple way.
Copy the .jar file to clipboard then add it to libs folder. To see libs folder in the project, choose the project from combobox above the folders.
then right click on the .jar file and click add as a library then choose a module then ok. You can see the .jar file in build.gradle file within dependencies block.
dependencies {
implementation fileTree(dir: 'libs', include: ['*.jar'])
implementation 'com.android.support:appcompat-v7:21.0.3'
implementation project(':okhttp-2.0.0')

Second way is that: We can add a .jar file to a module by importing this .jar file as a .jar module then add this module to any module we want.
import module ---> choose your .jar file --> than import as a .jar --
Then CTRL+ALT+SHIFT+S --> project sturure -->choose the module you want ato add a jar -->Dependencendies --> Module Dependency. build.gradle of the module will updated automatically.

On Windows 2003, to call another script without waiting, I used this:
$commandString = "start /b c:\\php\\php.EXE C:\\Inetpub\\wwwroot\\mysite.com\\phpforktest.php --passmsg=$testmsg";
pclose(popen($commandString, 'r'));
This only works AFTER giving changing permissions on cmd.exe
- add Read and Execute for IUSR_YOURMACHINE
(I also set write to Deny).
console.log( Object.keys( {'a':1,'b':2} ) );
ghostdog74's example provided the core of what I needed, since I've never written any vbs before and needed to do that. It's not perfect, but I fleshed out the example into a full script in case anyone finds it useful.

You can do either
From a view file:
<?php echo $this->request->here() ?>">
Which will give you the absolute url from the hostname i.e. /controller/action/params
Or
<?php echo Router::url(null, true) ?>
which should give you the full url with the hostname.
A class is a blueprint that is needed to make an object(= instance).
The difference between an object and an instance is, an object is a thing and an instance is a relation.
In other words, instance describes the relation of an object to the class that the object was made from.
Size of array cannot be modified. If you have to use an array, you can use:
System.arraycopy(src, srcpos, dest, destpos, length);
There are many ways to hide all elements which has certain class in javascript one way is to using for loop but here i want to show you other ways to doing it.
1.forEach and querySelectorAll('.classname')
document.querySelectorAll('.classname').forEach(function(el) {
el.style.display = 'none';
});
2.for...of with getElementsByClassName
for (let element of document.getElementsByClassName("classname")){
element.style.display="none";
}
3.Array.protoype.forEach getElementsByClassName
Array.prototype.forEach.call(document.getElementsByClassName("classname"), function(el) {
// Do something amazing below
el.style.display = 'none';
});
4.[ ].forEach and getElementsByClassName
[].forEach.call(document.getElementsByClassName("classname"), function (el) {
el.style.display = 'none';
});
i have shown some of the possible ways, there are also more ways to do it, but from above list you can Pick whichever suits and easy for you.
Note: all above methods are supported in modern browsers but may be some of them will not work in old age browsers like internet explorer.
$("li").click(function(){
alert($(this).attr("class"));
});

In my case a previous run of my app from VS reserved the URL. I could see this by running in a console:
netsh http show urlacl
to delete this reservation i ran this in an elevated console:
netsh http delete urlacl http://127.0.0.1:10002/
I found these steps here solved my problem.

If you want to just display some text in your .cshtml page, I do not recommend @Html.Label and also not to use the html label as well. The element represents a caption in a user interface. and you'll see that in the case of @Html.Label, a for attribute is added, referring to the id of a, possibly non-existent, element. The value of this attribute is the value of the model field, in which non-alphanumerics are replaced by underscores. You should use @Html.Display or @Html.DisplayFor, possibly wrapped in some plain html elements line span or p.
First check a Launch Activity is set in your 'manifest.xml
' file has:
<activity android:name=".{activityName}">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
If this is set correctly, next check your run/debug configuration is set to 'App
',
If the 'App' configuration is missing - you will need to add it by first selecting 'Edit Confurations'
If you do not have a 'App
' configuration you will need to create one, else select you 'App
' configuration and skip the creating steps. Also if your configuration is corrupt you may need to delete it but first backup your project. To delete a corrupt configuration, select it by expanding the 'Android App
' node and chose the '-
' button.
To create a new configuration, select the '+
' button and select 'Android App'
If you have just created the configuration you will be presented with the following default name value of 'Unnamed
' and module will have the value '<no module>
' then hit 'Apply
' and 'OK
'.
Set this the name to 'App
' and select 'app
' as the module.
Next select 'App
' as the run configuration and Run.
Thats it!
The following code can cause similar error:
using (var session = SessionFactory.OpenSession())
using (var tx = session.BeginTransaction())
{
movie = session.Get<Movie>(movieId);
tx.Commit();
}
Assert.That(movie.Actors.Count == 1);
You can fix it simply:
using (var session = SessionFactory.OpenSession())
using (var tx = session.BeginTransaction())
{
movie = session.Get<Movie>(movieId);
Assert.That(movie.Actors.Count == 1);
tx.Commit();
}
Here's a javascript example from mozilla:
var o = { a:0 } // `o` is now a basic object
Object.defineProperty(o, "b", {
get: function () {
return this.a + 1;
}
});
console.log(o.b) // Runs the getter, which yields a + 1 (which is 1)
I've used these A LOT because they are awesome. I would use it when getting fancy with my coding + animation. For example, make a setter that deals with an Number
which displays that number on your webpage. When the setter is used it animates the old number to the new number using a tweener. If the initial number is 0 and you set it to 10 then you would see the numbers flip quickly from 0 to 10 over, let's say, half a second. Users love this stuff and it's fun to create.
Example from sof
<?php
class MyClass {
private $firstField;
private $secondField;
public function __get($property) {
if (property_exists($this, $property)) {
return $this->$property;
}
}
public function __set($property, $value) {
if (property_exists($this, $property)) {
$this->$property = $value;
}
return $this;
}
}
?>

J2EE traditionally referred to products and standards released by Sun. For example if you were developing a standard J2EE web application, you would be using EJBs, Java Server Faces, and running in an application server that supports the J2EE standard. However since there is such a huge open source plethora of libraries and products that do the same jobs as well as (and many will argue better) then these Sun offerings, the day to day meaning of J2EE has migrated into referring to these as well (For instance a Spring/Tomcat/Hibernate solution) in many minds.
This is a great book in my opinion that discusses the 'open source' approach to J2EE http://www.theserverside.com/tt/articles/article.tss?l=J2EEWithoutEJB_BookReview
listView1.View = View.Details;
listView1.Columns.Add("Target No.", 83, HorizontalAlignment.Center);
listView1.Columns.Add(" Range ", 100, HorizontalAlignment.Center);
listView1.Columns.Add(" Azimuth ", 100, HorizontalAlignment.Center);
i also had same problem .. i drag column to left .. but now ok .. so let's say i have 283*196 size of listview ..... We declared in the column width -2 for auto width .. For fitting in the listview ,we can divide listview width into 3 parts (83,100,100) ...
Add this property to your grid-view : ShowHeaderWhenEmpty="True" it might help just check
You are referring to the type rather than the instance. Make 'Model' lowercase in the example in your second and fourth code samples.
Model.GetHtmlAttributes
should be
model.GetHtmlAttributes
'Millis since unix epoch' represents an instant, so you should use the Instant class:
private long toEpochMilli(LocalDateTime localDateTime)
{
return localDateTime.atZone(ZoneId.systemDefault())
.toInstant().toEpochMilli();
}
If you are using email password then you should replace it with app password.for setting APP password you need to enable the 2 step authentication before setting password which can be disabled later.
Also make sure that you have allowed less secure app in setting section.For additional info you can follow how to here
ReducedForm
is a type, so you cannot say
ReducedForm.iSimplifiedNumerator = iNumerator/iGreatCommDivisor;
You can only use the .
operator on an instance:
ReducedForm rf;
rf.iSimplifiedNumerator = iNumerator/iGreatCommDivisor;
if (itemdescription != null && itemdescription.length() > 0) {
pstmt2.setString(3, itemdescription.substring(0, Math.min(itemdescription.length(), 38)));
} else {
pstmt2.setString(3, "_");
}
As stated in the other answer, width: auto doesn't work due to the width being generated by the input's size attribute, which cannot be set to "auto" or anything similar.
There are a few workarounds you can use to cause it to play nicely with the box model, but nothing fantastic as far as I know.
First you can set the padding in the field using percentages, making sure that the width adds up to 100%, e.g.:
input {
width: 98%;
padding: 1%;
}
Another thing you might try is using absolute positioning, with left and right set to 0. Using this markup:
<fieldset>
<input type="text" />
</fieldset>
And this CSS:
fieldset {
position: relative;
}
input {
position: absolute;
left: 0;
right: 0;
}
This absolute positioning will cause the input to fill the parent fieldset horizontally, regardless of the input's padding or margin. However a huge downside of this is that you now have to deal with the height of the fieldset, which will be 0 unless you set it. If your inputs are all the same height this will work for you, simply set the fieldset's height to whatever the input's height should be.
Other than this there are some JS solutions, but I don't like applying basic styling with JS.
You can try this.
Workbooks("Tire.xls").Activate
ThisWorkbook.Sheets("Sheet1").Select
Cells(2,24).value=24
Here's the answer:
import numpy
num1 = 3.1400
num2 = 3.000
numpy.format_float_positional(num1, 3, trim='-')
numpy.format_float_positional(num2, 3, trim='-')
output "3.14" and "3"
trim='-'
removes both the trailing zero's, and the decimal.
I use method 3 because it's the most understandable for others (whenever you see an <a>
tag, you know it's a link) and when you are part of a team, you have to make simple things ;).
And finally I don't think it's useful and efficient to use JS simply to navigate to an other page.
MYSQL 8 does, in a way:
MYSQL 8 supports JSON tables, so you could load your results into a JSON variable and select from that variable using the JSON_TABLE() command.
I'm adding up to the original answer given by Guy which is still valid today (soon 2020).
Overriding the default docker registry, like you would do with maven
, is actually not a good practice.
When using maven
, you pull artifacts from Maven Central Repository through your local repository management system that will act as a proxy. These artifacts are plain, raw libs (jars) and it is quite unlikely that you will push jars with the same name.
On the other hand, docker images are fully operational, runnable, environments, and it makes total sens to pull an image from the Docker Hub, modify it and push this image in your local registry management system with the same name, because it is exactly what its name says it is, just in your enterprise context. In this case, the only distinction between the two images would precisely be its path!!
Therefore the need to set the following rule: the prefix of an image indicates its origin; by default if an image does not have a prefix, it is pulled from Docker Hub.
You can call get() with the path to Chrome. Below is an example - replace chrome_path with the correct path for your platform.
import webbrowser
url = 'http://docs.python.org/'
# MacOS
chrome_path = 'open -a /Applications/Google\ Chrome.app %s'
# Windows
# chrome_path = 'C:/Program Files (x86)/Google/Chrome/Application/chrome.exe %s'
# Linux
# chrome_path = '/usr/bin/google-chrome %s'
webbrowser.get(chrome_path).open(url)
You are providing a string representation of a dict to the DataFrame constructor, and not a dict itself. So this is the reason you get that error.
So if you want to use your code, you could do:
df = DataFrame(eval(data))
But better would be to not create the string in the first place, but directly putting it in a dict. Something roughly like:
data = []
for row in result_set:
data.append({'value': row["tag_expression"], 'key': row["tag_name"]})
But probably even this is not needed, as depending on what is exactly in your result_set
you could probably:
DataFrame(result_set)
read_sql_query
function to do this for you (see docs on this)Now use np.array_equal
. From documentation:
np.array_equal([1, 2], [1, 2])
True
np.array_equal(np.array([1, 2]), np.array([1, 2]))
True
np.array_equal([1, 2], [1, 2, 3])
False
np.array_equal([1, 2], [1, 4])
False
If you have several Java versions on your machine and you want to choose it dynamically at runtime, i.e, in my case, I have two versions:
ls -la /Library/Java/JavaVirtualMachines
drwxr-xr-x 3 root wheel 96B Nov 16 2014 jdk1.7.0_71.jdk/
drwxr-xr-x 3 root wheel 96B Mar 1 2015 jdk1.8.0_31.jdk/
You can change them by modifying the /etc/profile
content. Just add (or modify) the following two lines at the end of the file:
export JAVA_HOME=YOUR_JAVA_PATH/Contents/Home
export PATH=$JAVA_HOME/bin:$PATH
In my case, it should be like the following if I want to use:
Java 7:
export JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk1.7.0_71.jdk/Contents/Home
export PATH=$JAVA_HOME/bin:$PATH
Java 8:
export JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk1.8.0_31.jdk/Contents/Home
export PATH=$JAVA_HOME/bin:$PATH
After saving the file, please run source /etc/profile
and it should work. Here are results when I use the first and second option accordingly:
Java 7:
java -version
java version "1.7.0_71"
Java(TM) SE Runtime Environment (build 1.7.0_71-b14)
Java 8:
java -version
java version "1.8.0_31"
Java(TM) SE Runtime Environment (build 1.8.0_31-b13)
The process is similar if your java folder is located in different locations.
You can use ng-init
as shown below
<div class="TotalForm">
<label>B/W Print Total</label>
<div ng-init="{{BWCount=(oMachineAccounts|sumByKey:'BWCOUNT')}}">{{BWCount}}</div>
</div>
<div class="TotalForm">
<label>Color Print Total</label>
<div ng-init="{{ColorCount=(oMachineAccounts|sumByKey:'COLORCOUNT')}}">{{ColorCount}}</div>
</div>
and then use the local scope variable in other sections:
<div>Total: BW: {{BWCount}}</div>
<div>Total: COLOR: {{ColorCount}}</div>
Use case/esac
to test:
case "$var" in
"") echo "zero length";;

A solution to this problem could be to apply the filters on controller side :
$scope.tags = $filter('lowercase')($scope.tags);
Don't forget to declare $filter
as dependency.

If, for example, x = 5 and is stored as string, you can also just:
x = x + 0
and the new x would be stored as a numeric value.
If you are really looking to speed your code navigation, you might want to take a look at nWire for Java. It is a code exploration plugin for Eclipse. You can instantly see all the related artifacts. So, in that case, you will focus on the method call and instantly see all possible implementations, declarations, invocations, etc.
The DateFormat
class has a parse
method.

You could use ChromeOptions and set suitable argument:
options = ChromeOptions()
options.add_argument("--start-maximized")
driver = ChromeDriver(options)
This may happen due to the following reasons -
So by removing the implementation or adding them can remove this error. You can remove the "uses" code in the android manifest file.
Examples:
this wasted my 1 hour, cause I mistakenly added a class of wearable type, of course, I safe deleted that using refractor but it Didi not made changes to manifest file.
I used the firebase crashlytics code in my java project but I mistakenly deleted that in buld.gradle. Here below: implementation 'com.google.firebase:firebase-crashlytics:17.1.1'
The solution is in either BUILD>GRADLE or in AndroidManifest.xml, mostly.
I removed the float from the second div to make it work.
for using code, for example to check what modules in Hackerrank etc :
import os
os.system("pip list")
Just complementing @yuchaozh answer above that helped me solve it. (I don't have rep to comment)
Run this to know which java version you have
ls /Library/Java/JavaVirtualMachines/
You'll get an output like:
jdk1.8.0_111.jdk
Replace with your Java version and run this command to export the correct path.
export JAVA_HOME="/Library/Java/JavaVirtualMachines/<YOUR_JAVA_VERSION>/Contents/Home"
B+Trees are much easier and higher performing to do a full scan, as in look at every piece of data that the tree indexes, since the terminal nodes form a linked list. To do a full scan with a B-Tree you need to do a full tree traversal to find all the data.
B-Trees on the other hand can be faster when you do a seek (looking for a specific piece of data by key) especially when the tree resides in RAM or other non-block storage. Since you can elevate commonly used nodes in the tree there are less comparisons required to get to the data.
You can set the default value of your Id in your db to newsequentialid() or newid(). Then the identity configuration of EF should work.
My tomcat7 implementation is accepting strings as ISO-8859-1; despite the content-type of the HTTP request. The following solution worked for me when trying to correctly interpret characters like 'é' .
byte[] b1 = szP1.getBytes("ISO-8859-1");
System.out.println(b1.toString());
String szUT8 = new String(b1, "UTF-8");
System.out.println(szUT8);
When trying to interpret the string as US-ASCII, the byte info wasn't correctly interpreted.
b1 = szP1.getBytes("US-ASCII");
System.out.println(b1.toString());
You can define the PagerAdapter
like this then you will able to get any Fragment
in ViewPager
.
private class PagerAdapter extends FragmentPagerAdapter {
private final List<Fragment> mFragmentList = new ArrayList<>();
public PagerAdapter(FragmentManager fm) {
super(fm);
}
@Override
public Fragment getItem(int position) {
return mFragmentList.get(position);
}
@Override
public int getCount() {
return mFragmentList.size();
}
public void addFragment(Fragment fragment) {
mFragmentList.add(fragment);
}
}
To get the current Fragment
Fragment currentFragment = mPagerAdapter.getItem(mViewPager.getCurrentItem());
Just cast the entire sockaddr
structure to a sockaddr_in. Then you can use:
char *ip = inet_ntoa(their_addr.sin_addr)
To retrieve the standard ip representation.
You can use the annotate command to place text annotations at any x and y values you want. To place them exactly at the data points you could do this
import numpy
from matplotlib import pyplot
x = numpy.arange(10)
y = numpy.array([5,3,4,2,7,5,4,6,3,2])
fig = pyplot.figure()
ax = fig.add_subplot(111)
ax.set_ylim(0,10)
pyplot.plot(x,y)
for i,j in zip(x,y):
ax.annotate(str(j),xy=(i,j))
pyplot.show()
If you want the annotations offset a little, you could change the annotate
line to something like
ax.annotate(str(j),xy=(i,j+0.5))
I don't know of a global setting nither but you can try this:
Put this in your .bashrc to open vim with last edited file at last edited line
alias vil="vim +\"'\"0"
isFinite(String(n)) returns true for n=0 or '0', '1.1' or 1.1,
but false for '1 dog' or '1,2,3,4', +- Infinity and any NaN values.
One thing to keep in mind is that the relevant path here is the path relative to the file system location of your class... in your case TestGameTable.class. It is not related to the location of the TestGameTable.java file.
I left a more detailed answer here... where is resource actually located
Sometimes frameworks (like $resource/AngularJS) require an array as a query result, and you can't really have a response like {count:10,items:[...]}
in this case I store "count" in responseHeaders.
P. S. Actually you can do that with $resource/AngularJS, but it needs some tweaks.
Since TS 2.0, we have the ability to define visibility modifiers on constructors, so now we can do singletons in TypeScript just like we are used to from other languages.
Example given:
class MyClass
{
private static _instance: MyClass;
private constructor()
{
//...
}
public static get Instance()
{
// Do you need arguments? Make it a regular static method instead.
return this._instance || (this._instance = new this());
}
}
const myClassInstance = MyClass.Instance;
Thank you @Drenai for pointing out that if you write code using the raw compiled javascript you will not have protection against multiple instantiation, as the constraints of TS disappears and the constructor won't be hidden.
It has to be a constant - the value has to be computable at the time that the procedure is created, and that one computation has to provide the value that will always be used.
Look at the definition of sys.all_parameters
:
default_value
sql_variant
Ifhas_default_value
is 1, the value of this column is the value of the default for the parameter; otherwise,NULL
.
That is, whatever the default for a parameter is, it has to fit in that column.
As Alex K pointed out in the comments, you can just do:
CREATE PROCEDURE [dbo].[problemParam]
@StartDate INT = NULL,
@EndDate INT = NULL
AS
BEGIN
SET @StartDate = COALESCE(@StartDate,CONVERT(INT,(CONVERT(CHAR(8),GETDATE()-130,112))))
provided that NULL
isn't intended to be a valid value for @StartDate
.
As to the blog post you linked to in the comments - that's talking about a very specific context - that, the result of evaluating GETDATE()
within the context of a single query is often considered to be constant. I don't know of many people (unlike the blog author) who would consider a separate expression inside a UDF to be part of the same query as the query that calls the UDF.
Use LINQ:
Datagridview1.Columns.Cast<DataGridViewColumn>().ToList().ForEach(f => f.SortMode = DataGridViewColumnSortMode.NotSortable);
I had the same issue trying to install jquery-rails. The fix was
sudo apt-get install zlibc zlib1g zlib1g-dev
config
is another option:
widget1.config(bg='black')
widget2.config(bg='#000000')
or:
widget1.config(background='black')
widget2.config(background='#000000')
Look at this page: http://www.webcodingtech.com/javascript/change-cursor.php. Looks like you can access cursor off of style. This page shows it being done with the entire page, but I'm sure a child element would work just as well.
document.body.style.cursor = 'wait';
The below worked for me
element instanceof RenderedWebElement
should work.
You should try something like this
<Button
android:id="@+id/imageButton1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="@drawable/qrcode"/>
the android:background="@drawable/qrcode"
will do it

If you're using Windows Terminal then the killing process might be little less tedious.
I've been using windows terminal and kill PID
works fine for me to kill processes on the port as the new Windows Terminal supports certain bash commands. For example: kill 13300
So, the complete process will look like this-
netstat -ano | findstr :PORT
kill PID
For Example:
PS C:\Users\username> netstat -ano | findstr :4445
TCP 0.0.0.0:4445 0.0.0.0:0 LISTENING 7368
TCP [::]:4445 [::]:0 LISTENING 7368
PS C:\Users\username> kill 7368
PS C:\Users\username> netstat -ano | findstr :4445
PS C:\Users\username>
See when I typed the first command to list processes on the port it returned empty. That means all processes are killed now.
Update: kill
is an alias for Stop-Process. Thanks, @FSCKur for letting us know.
you can do it this way also
<?php
$csv= '\'' . join(array('lastname', 'email', 'phone'),'\',').'\'';
echo $csv;
?>
You can hide a part of JFrame that contains the swing controls which you want on another JFrame.
When the user clicks on a Jbutton the JFrame width increases and when he clicks on another same kind of Jbutton the JFrame comes to the default size.
JFrame myFrame = new JFrame("");
JButton button1 = new JButton("Basic");
JButton button2 = new JButton("More options");
// actionPerformed block code for button1 (Default size)
myFrame.setSize(400, 400);
// actionPerformed block code for button2 (Increase width)
myFrame.setSize(600, 400);
Instead of location.reload()
, simply use location.href = location.href
. It will not scroll to the previous position as location.reload()
does.
Note: This will not reload if there is any # in the URL
Your issue is in PHPMyAdmin itself. Some versions do not display the value of bit columns, even though you did set it correctly.
As mentioned, but with a code sample:
foreach(var item in collection.ToArray())
collection.Add(new Item...);
I use AngularJS v1.3.4
HTML:
<button ng-click="downloadPdf()" class="btn btn-primary">download PDF</button>
JS controller:
'use strict';
angular.module('xxxxxxxxApp')
.controller('xxxxController', function ($scope, xxxxServicePDF) {
$scope.downloadPdf = function () {
var fileName = "test.pdf";
var a = document.createElement("a");
document.body.appendChild(a);
a.style = "display: none";
xxxxServicePDF.downloadPdf().then(function (result) {
var file = new Blob([result.data], {type: 'application/pdf'});
var fileURL = window.URL.createObjectURL(file);
a.href = fileURL;
a.download = fileName;
a.click();
});
};
});
JS services:
angular.module('xxxxxxxxApp')
.factory('xxxxServicePDF', function ($http) {
return {
downloadPdf: function () {
return $http.get('api/downloadPDF', { responseType: 'arraybuffer' }).then(function (response) {
return response;
});
}
};
});
Java REST Web Services - Spring MVC:
@RequestMapping(value = "/downloadPDF", method = RequestMethod.GET, produces = "application/pdf")
public ResponseEntity<byte[]> getPDF() {
FileInputStream fileStream;
try {
fileStream = new FileInputStream(new File("C:\\xxxxx\\xxxxxx\\test.pdf"));
byte[] contents = IOUtils.toByteArray(fileStream);
HttpHeaders headers = new HttpHeaders();
headers.setContentType(MediaType.parseMediaType("application/pdf"));
String filename = "test.pdf";
headers.setContentDispositionFormData(filename, filename);
ResponseEntity<byte[]> response = new ResponseEntity<byte[]>(contents, headers, HttpStatus.OK);
return response;
} catch (FileNotFoundException e) {
System.err.println(e);
} catch (IOException e) {
System.err.println(e);
}
return null;
}
Just a reminder: Implicit type var
in multiple declaration is not allowed. There might be the following compilation errors.
var Foo = 0, Bar = 0;
Implicitly-typed variables cannot have multiple declarators
Similarly,
var Foo, Bar;
Implicitly-typed variables must be initialized
I'd suggest you use the newer assertThat()
style asserts, which can easily describe all kinds of negations and automatically build a description of what you expected and what you got if the assertion fails:
assertThat(objectUnderTest, is(not(someOtherObject)));
assertThat(objectUnderTest, not(someOtherObject));
assertThat(objectUnderTest, not(equalTo(someOtherObject)));
All three options are equivalent, choose the one you find most readable.
To use the simple names of the methods (and allow this tense syntax to work), you need these imports:
import static org.junit.Assert.*;
import static org.hamcrest.CoreMatchers.*;
You also can replace large text for email template at run time, here is an simple example for that.
DECLARE @xml NVARCHAR(MAX)
SET @xml = CAST((SELECT [column] AS 'td','',
,[StartDate] AS 'td'
FROM [table]
FOR XML PATH('tr'), ELEMENTS ) AS NVARCHAR(MAX))
select REPLACE((EmailTemplate), '[@xml]', @xml) as Newtemplate
FROM [dbo].[template] where id = 1
Reflection
has many uses. The one I am more familiar with, is to be able to create code on the fly.
IE: dynamic classes, functions, constructors - based on any data (xml/array/sql results/hardcoded/etc..)
The JavaDoc explains it very well:
With this option set to a non-zero timeout, a read() call on the InputStream associated with this Socket will block for only this amount of time. If the timeout expires, a java.net.SocketTimeoutException is raised, though the Socket is still valid. The option must be enabled prior to entering the blocking operation to have effect. The timeout must be > 0. A timeout of zero is interpreted as an infinite timeout.
SO_TIMEOUT
is the timeout that a read()
call will block. If the timeout is reached, a java.net.SocketTimeoutException will be thrown. If you want to block forever put this option to zero (the default value), then the read()
call will block until at least 1 byte could be read.
I was ultimately able to resolve the solution by setting the column type in the flat file connection to be of type "database date [DT_DBDATE]"
Apparently the differences between these date formats are as follow:
DT_DATE A date structure that consists of year, month, day, and hour.
DT_DBDATE A date structure that consists of year, month, and day.
DT_DBTIMESTAMP A timestamp structure that consists of year, month, hour, minute, second, and fraction
By changing the column type to DT_DBDATE the issue was resolved - I attached a Data Viewer and the CYCLE_DATE value was now simply "12/20/2010" without a time component, which apparently resolved the issue.
tl;dr script to update all installed packages
If you only want to upgrade one package, refer to @borgr's answer. I often find it necessary, or at least pleasing, to upgrade all my packages at once. Currently, pip doesn't natively support that action, but with sh scripting it is simple enough. You use pip list
, awk
(or cut
and tail
), and command substitution. My normal one-liner is:
for i in $(pip list -o | awk 'NR > 2 {print $1}'); do sudo pip install -U $i; done
This will ask for the root password. If you do not have access to that, the --user
option of pip
or virtualenv may be something to look into.
If the length is non zero, you can also
str[str.length() - 1] = '\0';
2019 modern browsers update
This is the approach I'd now recommend with a few caveats:
fetch('https://jsonplaceholder.typicode.com/todos/1')_x000D_

.then(blob => {_x000D_
const url = window.URL.createObjectURL(blob);_x000D_

2012 Original jQuery/iframe/Cookie based approach
Bluish is completely right about this, you can't do it through Ajax because JavaScript cannot save files directly to a user's computer (out of security concerns). Unfortunately pointing the main window's URL at your file download means you have little control over what the user experience is when a file download occurs.
I created jQuery File Download which allows for an "Ajax like" experience with file downloads complete with OnSuccess and OnFailure callbacks to provide for a better user experience. Take a look at my blog post on the common problem that the plugin solves and some ways to use it and also a demo of jQuery File Download in action. Here is the source
Here is a simple use case demo using the plugin source with promises. The demo page includes many other, 'better UX' examples as well.
$.fileDownload('some/file.pdf')
.done(function () { alert('File download a success!'); })
.fail(function () { alert('File download failed!'); });
Depending on what browsers you need to support you may be able to use https://github.com/eligrey/FileSaver.js/ which allows more explicit control than the IFRAME method jQuery File Download uses.
A better option
set my_message=Hello world
&& start cmd /c "@echo off & mode con cols=15 lines=2 & echo %my_message% & pause>nul"
Description:
lines=
amount of lines,plus 1
cols=
amount of characters in the message, plus 3 (However, minimum must be 15
)
cols
version:set my_message=Hello world
&& (echo %my_message%>EMPTY_FILE123 && FOR %? IN (EMPTY_FILE123 ) DO SET strlength=%~z? && del EMPTY_FILE123 ) && start cmd /c "@echo off && mode con lines=2 cols=%strlength% && echo %my_message% && pause>nul"
.val didnt work for me, because i'm grabbing the value attribute server side and the value wasn't always updated. so i used :
var counter = 0;
$('a.myClickableLink').click(function(event){
event.preventDefault();
counter++;
...
$('#myInput').attr('value', counter);
}
Hope it helps someone.
You can try this with your nav div
:
postion: fixed;
top: 0;
width: 100%;
an abstract class can have member variables that needs to be initialized,so they can be initialized in the abstract class constructor and this constructor is called when derived class object is initialized.
It's programmer preference. Personally, I love using this
since it explicitly marks the object members. Of course the _
does the same thing (only when you follow the convention)
For clarity purposes, I often use the select argument in subset
. With newer folks, I've learned that keeping the # of commands they need to pick up to a minimum helps adoption. As their skills increase, so too will their coding ability. And subset is one of the first commands I show people when needing to select data within a given criteria.
Something like:
> subset(mtcars, select = c("mpg", "cyl", "vs", "am"))
mpg cyl vs am
Mazda RX4 21.0 6 0 1
Mazda RX4 Wag 21.0 6 0 1
Datsun 710 22.8 4 1 1
....
I'm sure this will test slower than most other solutions, but I'm rarely at the point where microseconds make a difference.
the best way to find out all the combinations for large number of lists is:
import itertools
from pprint import pprint
inputdata = [
['a', 'b', 'c'],
['d'],
['e', 'f'],
]
result = list(itertools.product(*inputdata))
pprint(result)
the result will be:
[('a', 'd', 'e'),
('a', 'd', 'f'),
('b', 'd', 'e'),
('b', 'd', 'f'),
('c', 'd', 'e'),
('c', 'd', 'f')]
You can use ancestor
. I find that this is easier to read because the element you are actually selecting is at the end of the path.
//span[contains(text(),'someText')]/ancestor::div[contains(@class, 'measure-tab')]
Either Cybernate or OMG Ponies solution will work. The fundamental problem is that the DATE_FORMAT()
function returns a string, not a date. When you wrote
(Select Date_Format(orders.date_purchased,'%m/%d/%Y')) As Date
I think you were essentially asking MySQL to try to format the values in date_purchased
according to that format string, and instead of calling that column date_purchased
, call it "Date". But that column would no longer contain a date, it would contain a string. (Because Date_Format()
returns a string, not a date.)
I don't think that's what you wanted to do, but that's what you were doing.
Don't confuse how a value looks with what the value is.
For me this was because I was using a debug and release build variant. I added the new folders src/debug/res/layout/some_layout.xml file manually, and it didn't recognize the URI. I switched the build variant to release, and then back to debug. This caused Android Studio to reload something, and the error went away.
EDIT: Also check that you have the correct filename. I had this issue again by adding a debug AndroidManifest.xml, but mistakenly named it AndroidManifest.xml.xml.
The best way to handle the LazyInitializationException
is to use the JOIN FETCH
directive for all the entities that you need to fetch along.
Anyway, DO NOT use the following Anti-Patterns as suggested by some of the answers:
Sometimes, a DTO projection is a better choice than fetching entities, and this way, you won't get any LazyInitializationException
.
Actually, You can achieve this with current typescript:
type Grow<T, A extends Array<T>> = ((x: T, ...xs: A) => void) extends ((...a: infer X) => void) ? X : never;
type GrowToSize<T, A extends Array<T>, N extends number> = { 0: A, 1: GrowToSize<T, Grow<T, A>, N> }[A['length'] extends N ? 0 : 1];
export type FixedArray<T, N extends number> = GrowToSize<T, [], N>;
Examples:
// OK
const fixedArr3: FixedArray<string, 3> = ['a', 'b', 'c'];
// Error:
// Type '[string, string, string]' is not assignable to type '[string, string]'.
// Types of property 'length' are incompatible.
// Type '3' is not assignable to type '2'.ts(2322)
const fixedArr2: FixedArray<string, 2> = ['a', 'b', 'c'];
// Error:
// Property '3' is missing in type '[string, string, string]' but required in type
// '[string, string, string, string]'.ts(2741)
const fixedArr4: FixedArray<string, 4> = ['a', 'b', 'c'];
EDIT (after a long time)
This should handle bigger sizes (as basically it grows array exponentially until we get to closest power of two):
type Shift<A extends Array<any>> = ((...args: A) => void) extends ((...args: [A[0], ...infer R]) => void) ? R : never;
type GrowExpRev<A extends Array<any>, N extends number, P extends Array<Array<any>>> = A['length'] extends N ? A : {
0: GrowExpRev<[...A, ...P[0]], N, P>,
1: GrowExpRev<A, N, Shift<P>>
}[[...A, ...P[0]][N] extends undefined ? 0 : 1];
type GrowExp<A extends Array<any>, N extends number, P extends Array<Array<any>>> = A['length'] extends N ? A : {
0: GrowExp<[...A, ...A], N, [A, ...P]>,
1: GrowExpRev<A, N, P>
}[[...A, ...A][N] extends undefined ? 0 : 1];
export type FixedSizeArray<T, N extends number> = N extends 0 ? [] : N extends 1 ? [T] : GrowExp<[T, T], N, [[T]]>;
This shows you how to
DOM
Nodes
with XPath
Nodes
. We will call the code with the following statement
processFilteredXml(xmlIn, xpathExpr,(node) -> {/*Do something...*/;});
In our case we want to print some creatorNames
from a book.xml
using "//book/creators/creator/creatorName"
as xpath to perform a printNode
action on each Node that matches the XPath
.
Full code
@Test
public void printXml() {
try (InputStream in = readFile("book.xml")) {
processFilteredXml(in, "//book/creators/creator/creatorName", (node) -> {
printNode(node, System.out);
});
} catch (Exception e) {
throw new RuntimeException(e);
}
}
private InputStream readFile(String yourSampleFile) {
return Thread.currentThread().getContextClassLoader().getResourceAsStream(yourSampleFile);
}
private void processFilteredXml(InputStream in, String xpath, Consumer<Node> process) {
Document doc = readXml(in);
NodeList list = filterNodesByXPath(doc, xpath);
for (int i = 0; i < list.getLength(); i++) {
Node node = list.item(i);
process.accept(node);
}
}
public Document readXml(InputStream xmlin) {
try {

DocumentBuilder db = dbf.newDocumentBuilder();
return db.parse(xmlin);

Object eval = expr.evaluate(doc, XPathConstants.NODESET);
return (NodeList) eval;
} catch (Exception e) {
throw new RuntimeException(e);
}
}
private void printNode(Node node, PrintStream out) {

StreamResult result = new StreamResult(new StringWriter());
DOMSource source = new DOMSource(node);
transformer.transform(source, result);
String xmlString = result.getWriter().toString();
out.println(xmlString);
} catch (Exception e) {
throw new RuntimeException(e);

On your branch - say master, pull and allow unrelated histories
git pull origin master --allow-unrelated-histories
Worked for me.
In this thread, Dianne Hackborn tells us we can get info out of the AndroidManifest using aapt.
I whipped up this quick unix command to grab the version info:
aapt dump badging my.apk | sed -n "s/.*versionName='\([^']*\).*/\1/p"
i'd suggest shorter and faster approach:
printf("%.2f", ((signed long)(fVal * 100) * 0.01f));
this way you won't overflow int, plus multiplication by 100 shouldn't influence the significand/mantissa itself, because the only thing that really is changing is exponent.

You could print the backspace character \b
as many times as the characters which were printed before.
System.out.print("hello");
Thread.sleep(1000); // Just to give the user a chance to see "hello".
System.out.print("\b\b\b\b\b");
System.out.print("world");
Note: this doesn't work flawlessly in Eclipse console in older releases before Mars (4.5). This works however perfectly fine in command console. See also How to get backspace \b to work in Eclipse's console?
Global variables are as bad as you make them, no less.
If you are creating a fully encapsulated program, you can use globals. It's a "sin" to use globals, but programming sins are laregly philosophical.
If you check out L.in.oleum, you will see a language whose variables are solely global. It's unscalable because libraries all have no choice but to use globals.
That said, if you have choices, and can ignore programmer philosophy, globals aren't all that bad.
Neither are Gotos, if you use them right.
The big "bad" problem is that, if you use them wrong, people scream, the mars lander crashes, and the world blows up....or something like that.
Aside from agreeing with the design observations of the previous commenters, none of the solutions were clean enough for me. .Net 4 provides Dispatcher
and Task
classes which make delaying execution on the current thread pretty simple:
static class AsyncUtils
{
static public void DelayCall(int msec, Action fn)
{
// Grab the dispatcher from the current executing thread
Dispatcher d = Dispatcher.CurrentDispatcher;
// Tasks execute in a thread pool thread
new Task (() => {
System.Threading.Thread.Sleep (msec); // delay
// use the dispatcher to asynchronously invoke the action
// back on the original thread
d.BeginInvoke (fn);
}).Start ();
}
}
For context, I'm using this to debounce an ICommand
tied to a left mouse button up on a UI element. Users are double clicking which was causing all kinds of havoc. (I know I could also use Click
/DoubleClick
handlers, but I wanted a solution that works with ICommand
s across the board).
public void Execute(object parameter)
{
if (!IsDebouncing) {
IsDebouncing = true;
AsyncUtils.DelayCall (DebouncePeriodMsec, () => {
IsDebouncing = false;
});
_execute ();
}
}
